Over 70% of equine fatalities on Victorian racetracks can be attributed primarily to catastrophic joint injury. Of these cases, injury to the fetlock joint is the most common. An understanding of the loads imparted on the structures in this joint will improve our understanding of the consequences of interventions and treatments. Previous studies in human biomechanics provide a reliable pathway to determining these loads.

Gait analysis involves the use of motion capture systems and force transducers to determine both the positions of all of the joints of an animal in motion and the reaction load observed when limbs are in contact with the ground (Fig. 1a). The results of gait analysis allow the estimation of the net torques about each joint. A separate 3D model of the musculoskeletal system (Fig. 1b) is then forced to behave in the same manner as the experimental results, yielding an estimate of the loads in each separate muscle structure. Finally these muscle forces are employed in a detailed 3D stress model of the joint to predict contact stresses (Fig. 1c).

This project will yield three such joint stress models, highly specific to three racehorses. These models will be able to predict some of the causes of tendon and bone failures as well as the outcomes of preventative measures.
